would like to ask, but i would like to get to the closure. >> i know you have a fustian. >> just one, madam chair. on the surveillance front, i hope we can do this with just a yes or no answer and i know senator feinstein wants to move on. last year, the nsa director was at a conference and he was asked about the nsa surveillance of america. he replied, "the story that we have millions or hundreds of millions dossiers on people is completely false." having served on the committee now for a dozen years, i don't really know what a dossier is in this context. so what i wanted to see, if you could give me a yes or no answer to the question, does the nsa collect any type of data at all on millions or hundreds of millions of americans? >> no, sir. >> it does not? >> not wittingly. there are cases where they could inadvertently perhaps collect but not willingly.
